A criminal complaint dated June 22, 2017, alleges that Keith Lane Hawkins, the man accused of killing a Newton Mother and her 4-year-old daughter, failed to register as a sex offender within three days of coming to Harvey County.

Hawkins has a prior juvenile conviction of aggravated indecent liberties with a child in McPherson County. Records of that crime are sealed.

Late Tuesday morning, the bodies of 24-year-old Alyssa Runyon and her 4-year-old daughter, Zaylynn Paz, were found by Runyon's ex-boyfriend in bedrooms of a duplex on Roanoke Ct.

Hawkins was later arrested after a chase and crash in Taylor, Texas.

Authorities have arrested a suspect in Texas after a mother and her 4-year-old daughter were found dead in a Newton home on Tuesday.

According to Newton police, 19-year-old Keith Lane Hawkins was taken into custody in Taylor, Texas, at about 5:25 p.m. The suspect was driving the victim's vehicle when he arrived at a family member's home.

Officers in Taylor tried to pull Hawkins over, which led to a chase that ended when he wrecked his vehicle.

Officers in Newton were called just after 11 a.m. to the report of two people found dead at 15 Roanoke Ct. Chief Eric Murphy said the mother's ex-boyfriend called 911 after he went to check on her because she wasn't answering her phone.

Officers arrived to find the bodies of 24-year-old Alyssa Runyon and her 4-year-old daughter, Zaylynn Paz, in bedrooms of the duplex. Police said there was no forced entry into the home, which happened overnight at a Duplex.

Chief Murphy said Runyon had been strangled and her daughter was stabbed.

"This was a targeted incident and not necessarily a random act that, you know, someone broke into someone's house and committed this. There's some sort of relationship between the suspect and the victims."

The Kansas Bureau of Investigation is assisting.

Tuesday's double homicide comes less than six months after a gunman killed three people and was fatally wounded by a Newton officer.

An online fund has been set up to help Runyon's family with expenses and assist with anything her other child may need.
